■ Ah, Super Bowl Sunday — the day we gather around the TV set, shovel thousands of calories into our faces and pretend we’re down with football, even if we don’t know a nickel defense from a Quarter Pounder. This year’s big game pits the New England Patriots against the Atlanta Falcons, but it’s about so much more than burly guys pummeling each other on fake grass. There’s the wacky commercials and, of course, the halftime show, which will have Lady Gaga rocking out on the edge of glory at NRG Stadium in Houston. Pregame coverage beings at 11 a.m., the game begins at about 6:30 p.m, Fox.
